Abstract

The rotor combination of a kind of 30-50 horsepower of the utility model double-screw air compressor, relates to the air compressing assembly of air compressor.This rotor combination has a pair of intermeshing female rotor and male rotor, and female rotor is established 6 left-handed teeth, and male rotor is established the tooth of 5 dextrorotation; The coordinate analytic value that forms each section of curved section of female rotor profile of tooth is, the 1st point: X=-30.873Y=-37.208; The 299th point: X=16.787Y=-45.341; The coordinate analytic value that forms each section of curved section of male rotor profile of tooth is, the 1st point: X=-0.000Y=61.212; The 301st point: X=58.216Y=18.916.Its female rotor and male rotor molded line, containing isolated point and straight line, do not have good combination property; Noise is low; Easily processing, easy to use.

Description

A kind of rotor combination of 30-50 horsepower double-screw air compressor
Technical field
The utility model relates to a kind of air compressing assembly of air compressor.
Background technique
Double-screw air compressor utilizes female rotor, the male rotor continuous wave output pressurized air of conjugation engagement running in cavity.The feature of female rotor, male rotor profile has determined performance and the efficiency of compressor.The manufacturer of double-screw air compressor is all devoted to the molded line research of yin, yang rotor flute profile now, for example to disclose the patent No. be ZL200820056997.2 to Chinese utility model patent specification CN201180654Y, name is called the technological scheme of " screw rotor of double-screw air compressor ", proposes this screw rotor and comprises a pair of intermeshing female rotor and male rotor; Wherein: female rotor is established 6 teeth, the top circle of its profile from the top circle of a tooth to next tooth is comprised of three circular arc lines, arc envelope line, straight line (junction of this arc envelope line and this straight line is isolated point), a cycloid and two circular arc lines in turn; Male rotor is established 4 teeth, and the root circle of its profile from the root circle of a tooth to next tooth is comprised of two arc envelope lines, two circular arc lines, two cycloids, circular arc line junction of a cycloid and this circular arc line (be isolated point) and a circular arc line in turn.The document discloses the coordinate analytic value that forms each section of curved section of female rotor profile of tooth and the coordinate analytic value that forms each section of curved section of male rotor profile of tooth.The disclosed technological scheme of the document has can reduce fluid dynamic loss and reduction noise, and leakage triangle area is little.Laterally reveal the advantages such as little; But its female rotor and male rotor molded line contain isolated point, even straight line, is difficult for processing.
Model utility content
The utility model aims to provide a kind of female rotor and male rotor molded line containing isolated point and straight line, the easy rotor combination of the 30-50 horsepower double-screw air compressor of processing.
The technical solution of the utility model is: a kind of rotor combination of 30-50 horsepower double-screw air compressor, there are a pair of intermeshing female rotor and male rotor, and female rotor is established 6 left-handed teeth, and male rotor is established the tooth of 5 dextrorotation; The coordinate analytic value that forms each section of curved section of female rotor profile of tooth is:

Adopt the molded line structure of the coordinate figure formation of above-mentioned yin, yang rotor, as shown in Figure 2: on female rotor 1, each tooth is provided with tooth top circular arc ab, connection circular arc bc, arc envelope line cd, arc envelope line de, arc envelope line ef, pendulum point protection circular arc fg.On male rotor 2, each tooth is provided with corresponding with each circular arc of each tooth on above-mentioned female rotor 1 respectively circular arc, tooth root circular arc AB, arc envelope line BC, transition arc CD, tooth top circular arc DE, pendulum point protection circular arc EF, arc envelope line FG.
Sealability between female rotor 1 and male rotor 2 between cog, volume, by three wider sealing strips, stop pressurized gas to leak to low voltage terminal, and selected less leakage triangle, and all tooth curve forms by circular arc and arc envelope line, and each tooth curve has been stopped isolated point and straight line.In above-mentioned molded line engagement process, be not a linear sealing but in several regions, realize multi-sealed to the flank of tooth of the flank of tooth completely, adopt excessively compared with small arc-shaped, leakage triangle is little, leaks few.Male rotor 2 tooth top three-arcs connect, and female rotor 1 tooth top three-arc meshes with arc envelope line entirely.It is streamlined that all tie points of molded line of female rotor 1 and male rotor 2 are all that rounding off is, and all cycloids form point circular arc protection.
The above, be only the utility model preferred embodiment, with this, do not limit the scope that the utility model is implemented, and the equivalence of doing according to the technical solution of the utility model and description changes and modifies, and all should belong to the scope that the utility model is contained.
